The Green Corridors Plan (Eixos Verds<\/em>\u00a0Plan), proposed by the Barcelona City Council, aims to enhance urban well-being, environmental sustainability, and resilience by transforming one in every three streets into green corridors. Although initially designed for city-wide implementation, only the first phase, focused on the centric Eixample district, has been completed, and the overall plan implementation has been postponed. Our aim is to evaluate the health co-benefits of implementing the\u00a0Green Corridors<\/em> plan citywide, focusing on the direct effects of increased exposure to greenness and the impact of temperature reduction on mortality.<\/p>\n

We conducted a comprehensive Health Impact Assessment (HIA) considering direct effects of expanding green spaces (GS) and the impact on temperature reduction. Preventable mortality at the census tract level for adult residents was estimated, and to address uncertainties, we performed Monte Carlo iterations. We computed the percentage increase in GS (land use) and tree cover and converted them into Normalized Difference Vegetation Index (NDVI) to conduct the HIA, employing a Generalized Additive Model (GAM). We used the Weather Research and Forecasting model (WRF) coupled with the urban parameterizations \u201cBuilding Effect Parameterization\u201d (BEP) and \u201cBuilding Energy Model\u201d (BEM) for temperature modelling. Hourly temperatures from 25\/06\/2015 to 25\/07\/2015 were simulated, both with and without\u00a0Green Corridors<\/em> Plan implementation.<\/p>\n

City-wide implementation of the\u00a0Green Corridors<\/em> plan would increase average GS by 3.64\u202f% (IQR: 2.17\u202f% \u2212 4.40\u202f%) and NDVI by 0.286 (IQR: 0.256\u20130.304) per census tract. This could potentially prevent 178 premature deaths annually (95\u202f% CI: 116\u2013247), equating to 13 deaths per 100,000 inhabitants (95\u202f% CI: 9\u201319). The average daily temperature reduction per census tract was estimated at 0.05\u202f\u00b0C, with a maximum reduction of 0.42\u202f\u00b0C. Temperature reduction could potentially prevent 5 deaths during the simulated month. Additionally, we estimated a mean decrease in the thermal stress of 0.11\u202f\u00b0C, reaching up to 1.48\u202f\u00b0C at its peak.<\/p>\n

The\u00a0Green Corridors<\/em>\u00a0plan can make significant contributions to a healthier urban environment. To address climate and especially heat impacts, complementary strategies to achieve more substantial temperature reduction are needed. Overall, our findings underscore the potential of nature-based solutions (NbS), exemplified by the\u00a0Green Corridors<\/em>\u00a0Plan, in creating more sustainable and health-promoting urban environments.<\/p>\n

El Pla d\u2019Eixos Verds, proposat per l’Ajuntament de Barcelona, t\u00e9 com a objectiu millorar el benestar urb\u00e0, la sostenibilitat ambiental i la resili\u00e8ncia transformant un de cada tres carrers en corredors verds. Tot i que inicialment es va dissenyar per a una implementaci\u00f3 a tota la ciutat, nom\u00e9s s’ha completat la primera fase, centrada al districte c\u00e8ntric de l’Eixample, i la implementaci\u00f3 general del pla s’ha posposat. El nostre objectiu \u00e9s avaluar els co-beneficis per a la salut de la implementaci\u00f3 del Pla d\u2019Eixos Verds a escala urbana, centrant-nos en els efectes directes de l\u2019augment de l\u2019exposici\u00f3 a la vegetaci\u00f3 i en l\u2019impacte de la reducci\u00f3 de la temperatura en la mortalitat.<\/p>\n

Hem realitzat una Avaluaci\u00f3 d\u2019Impacte en la Salut (AIS) completa, considerant els efectes directes de l\u2019expansi\u00f3 dels espais verds (EV) i el seu impacte en la reducci\u00f3 de la temperatura. S’ha estimat la mortalitat prevenible a nivell de secci\u00f3 censal per als residents adults i, per abordar les incerteses, s\u2019han dut a terme iteracions de Monte Carlo. Hem calculat l\u2019augment percentual dels EV (\u00fas del s\u00f2l) i la cobertura arb\u00f2ria, i els hem convertit en l\u2019\u00edndex de vegetaci\u00f3 de difer\u00e8ncia normalitzada (NDVI) per dur a terme l\u2019AIS mitjan\u00e7ant un Model Additiu Generalitzat (GAM). Per a la modelitzaci\u00f3 de la temperatura, hem utilitzat el model Weather Research and Forecasting (WRF) amb les parametritzacions urbanes \u201cBuilding Effect Parameterization\u201d (BEP) i \u201cBuilding Energy Model\u201d (BEM). Es van simular les temperatures hor\u00e0ries del 25\/06\/2015 al 25\/07\/2015, tant amb com sense la implementaci\u00f3 del Pla d\u2019Eixos Verds.<\/p>\n

L\u2019aplicaci\u00f3 del Pla d\u2019Eixos Verds a tota la ciutat augmentaria els EV en un 3,64 % (IQR: 2,17 % \u2013 4,40 %) i el NDVI en 0,286 (IQR: 0,256 \u2013 0,304) per secci\u00f3 censal. Aix\u00f2 podria prevenir potencialment 178 morts prematures anuals (IC 95 %: 116\u2013247), equivalent a 13 morts per cada 100.000 habitants (IC 95 %: 9\u201319). La reducci\u00f3 mitjana di\u00e0ria de la temperatura per secci\u00f3 censal s\u2019ha estimat en 0.05 \u00b0C, amb una reducci\u00f3 m\u00e0xima de 0.42 \u00b0C. Aquesta reducci\u00f3 podria prevenir 5 morts durant el mes simulat. A m\u00e9s, s\u2019ha estimat una disminuci\u00f3 mitjana de l\u2019estr\u00e8s t\u00e8rmic de 0.11 \u00b0C, arribant fins a 1.48 \u00b0C en el seu punt m\u00e0xim.<\/p>\n

El Pla d\u2019Eixos Verds pot contribuir de manera significativa a un entorn urb\u00e0 m\u00e9s saludable. Per abordar l\u2019impacte clim\u00e0tic i, especialment, l\u2019escalfament urb\u00e0, calen estrat\u00e8gies complement\u00e0ries per aconseguir una reducci\u00f3 de la temperatura m\u00e9s substancial. En general, els nostres resultats destaquen el potencial de les solucions basades en la natura (SbN), exemplificat pel Pla d\u2019Eixos Verds, per crear entorns urbans m\u00e9s sostenibles i beneficiosos per a la salut.<\/p>\n
